Risks & Considerations
Regulatory & FERC Oversight
Midstream projects often face lengthy legal battles and strict FERC filings that can delay multi-billion dollar pipeline expansions and LNG terminal startups.
Interest Rate Sensitivity
High-yield midstream assets are capital intensive. Rising interest rates can increase borrowing costs and make yield spreads less attractive compared to Treasuries.
Volume & Re-contracting Risk
While 91% of revenue is fee-based, the "take-or-pay" nature of contracts means that long-term volume declines or expiration without renewals can threaten cash flow.
Energy Transition Drag
Long-term fossil fuel demand trends and ESG mandates may impact the terminal value of legacy crude and refined product storage assets over the next decade.
